Rising roughly 1,000 feet in elevation, Mt. Holyoke Range State Park straddles the seven-mile ridge that runs from Hadley to Belchertown. The ridge is a patchwork of state, town and private lands. Parcels acquired by the state since the 1970's bring the park to over 3,000 acres. The Notch Visitor Center, located on Route 116 in Amherst, is open daily.
